Welcome to the community, @Sachisuta_Dasa!
Unfortunately, there’s no way to automatically jump to the bottom row.
If your records are UNGROUPED, you can click into the first row, and then hit “command down arrow” (Mac) or “control down arrow” (Windows) to jump to the bottom row.
However, this will not work if your records are grouped. If your records are grouped, this will only jump you to the bottom of the first group.
You can see a list of other keyboard shortcuts by going into your base, clicking on “Help”, and choosing “Keyboard Shortcuts”.
Unfortunately, the keyboard shortcuts are not as comprehensive as I would like them to be, but there are a few good ones in there.
